Predict Method for bma Objects
Description
Expected value of prediction based on 'bma' object
Usage
## S3 method for class 'bma'
predict(object, newdata = NULL, exact = FALSE, topmodels = NULL, ...)
Arguments
object 
a bma object  see 
newdata 
An optional data.frame, matrix or vector containing variables with which to predict. If omitted, then (the expected values of) the fitted values are returned. 
exact 
If 
topmodels 
index of the models with whom to predict: for instance,

... 
further arguments passed to or from other methods. 
Value
A vector with (expected values of) fitted values.

Examples
data(datafls)
mm=bms(datafls,user.int=FALSE)
predict(mm) #fitted values based on MCM frequencies
predict(mm, exact=TRUE) #fitted values based on best models
predict(mm, newdata=1:41) #prediction based on MCMC frequencies
predict(mm, newdata=datafls[1,], exact=TRUE) #prediction based on a data.frame
# the following two are equivalent:
predict(mm, topmodels=1:10)
predict(mm[1:10], exact=TRUE)
